multilib: Remove FileMultilibMethod class

In order to do something meaningful, the class needs to be instantiated
with arguments pointing the blacklist and whitelist.

The `file` multilib method used via `pungi-koji` or `pungi` directly has
no way to pass those in.

The only way this class can be useful would be if someone actually
imported the class directly in their own code. Pungi is not meant to be
used as a library though, so this is not really a supported use case.

Not to mention that the `select` method always returned `False`.
